To do whatever we wish, we must try to be free, responsible (or responsive), and strive for perfection. (although perfection is a goal and not a state of being)

The Source (Tao, God, Goddess, Chaos) frees us!Strive for perfection or excellence and the Source shall reward you if you become Her favorites.

Master of the universe are they who wield ultimate power through mastery of themselves, their emotions, and the Source.

Note: I had to do very little revision. The fictional Sith are almost identical in philosophy to their "Left-hand path" (or whatever) counterparts. Fortunately the modern Sithist isn't bound by a code.
